  • Three areas of obstruction standards to discuss. Also, talk about other useful information.
  • Low Profile Barricade Brief

    1. 1. FAA SAFETYREQUIREMENTS FORAIRFIELD CONSTRUCTIONBARRICADES
    2. 2. FAA Safety Requirements forAirfield Construction Barricades
    3. 3. Airport Construction BarricadesBarricades are used to keep aircraft out of closed areas and to keepconstruction vehicles out of active movement areas. They look the same inboth situations. Vehicle operators need to pay close attention when drivingthrough or around barricades to make sure you are not entering an activemovement area. 3
    4. 4. Airport Construction BarricadesWhen construction activity is being conducted on a taxiway adjacent to anactive runway, barricades are normally installed along the runway holdingposition marking. Do not drive through the barricades without ATCT clearancein this situation or you will be committing a V/PD Runway Incursion. 4
    5. 5. Preventing V/PDsConstruction vehicles normally drive through barricades to enter and leaveconstruction sites. Sometimes barricades are installed close together toprevent vehicles from inadvertently entering an active portion of the movementarea. Do not remove barricades to drive through. You may be entering anactive movement area without clearance. 5
    6. 6. Barricades/Red LightsBarricades are used to mark closed pavement and keep aircraft from enteringthe closed area. 6
    7. 7. Barricades/Red LightsAC 150/5370-2E, Par 3-8 b) states, “With taxiways, place an “X” at theentrance of the closed taxiway.” The use of an “X” provides a good visualreference of closed taxiways to pilots flying over the airport before landing. 7
    8. 8. Barricades/Red Lights A1 A Installing the Temporary “X” barricades 200’ from runway centerline would be more visible to pilots compared to A1 locating them on the holdline. A1 20 - 2 A 2  A1 A AUse a temporary “X” at the entrance to the runway exit from the runway. 8
    9. 9. Barricades/Red Lights A1 A 200’ A1 A1 20 - 2 A 2  A1 A AInstalling barricades 200’ from the runway centerline would better identify theclosed runway exit to pilots during both day and night conditions. However,barricades must be the low mass easily collapsible type if located in the runwaysafety area. 9
    10. 10. Example of Problem – ConstructionThe barricades for this construction area are at the entrance to the closedtaxiway in the far background. Additional barricades should have also beenplaced at the construction site in this situation. A pilot could have missedseeing the barricades if they approached the taxiway from the apron. Thiscould also be a potentially dangerous situation for vehicle operators at night. 10
    11. 11. Example of Problem – ConstructionBe sure that the retroreflective stripes on barricades are facing in the rightdirection. The stripes at this location are facing the closed area. 11
    12. 12. Barricades/Red LightsBarricades used to mark construction areas or closed pavement must be aslow as possible to the ground; low mass; easily collapsible upon contact with anaircraft or any of its components; and weighted or sturdily attached to thesurface to prevent displacement from prop wash, jet blast, wing vortex, or othersurface wind currents. (AC 150/5370-2E, Par 3-9 b) This particular barricade isdesigned to be filled with water. 12
    13. 13. Example of Problem – ConstructionRailroad ties are not to be used on runways, which includes the runway safetyarea. (AC 150/5370-2E, Par 3-9 b) 13
    14. 14. Barricades/Red Lights Movement A rea Non-movement AreaThe use of concrete jersey barricades in the movement areas (adjacent totaxiways) is not acceptable. (AC 150/5370-2E, Par 3-9 b) 14
    15. 15. Barricades/Red LightsLow profile, low mass barricades must be used to mark the boundary ofconstruction areas that are adjacent to open taxiways. 15
    16. 16. Barricades/Red LightsHighway type barricades may be too high for use adjacent to movement areas. 16
    17. 17. Barricades/Red Lights Is there a chance that this barricade could be hit by a prop?Props on twin engine aircraft could hit taller highway type barricades. 17
    18. 18. Barricades/Red LightsSome aircraft have engines that are located fairly close to the ground, limitingthe height of barricades used to mark construction areas adjacent to movementareas used by these aircraft. The possibility of engine ingestion is also aconcern when placing barricades adjacent to taxi routes. 18
    19. 19. Taxiway Ending MarkerThe use of a temporary taxiway ending marker to supplement barricades is agood practice and highly recommended to mark closed taxiways. Thesemarkers are visible to pilots from a farther distance than the typical low profiletype barricades. 19
    20. 20. Barricades/Red LightsUse highly reflective barriers with flashing or steady-burning red lights tobarricade taxiways leading to closed runways. Evaluate all operating factorswhen determining how to mark temporary closures that can last from 10 to 15minutes to a much longer period of time. However, we strongly recommendthat, even for closures of relatively short duration, major taxiway/runwayintersections be identified with barricades spaced no greater than 20 feet apart. (AC 150/5370-2E, Par 3-9 b) 20
    21. 21. Example of Problem – ConstructionIn accordance with AC 150/5370-2E, Operational Safety on Airports DuringConstruction, Par 3-9a & 3-9b, yellow lights are no longer acceptable forlighting construction areas on movement areas and nonmovement areas.(Became effective October 2004) 21
    22. 22. Barricades/Red LightsRed lights for marking construction areas are required because of a problemwith pilots confusing flashing yellow construction lights with in-pavementRunway Guard Lights. 22
    23. 23. Barricades/Red LightsThis photo shows an example of a flashing red light that is visible 360 degrees.These type of red lights are recommended. 23
    24. 24. Barricades/Red LightsIf you choose a flat light fixture rather than a 360 degree light, rotate one of thelights 90 degrees as shown in this photo. 24
    25. 25. Barricades/Red LightsBarricades, warning lighting, and reflectors must be adequate to keep aircraftout of construction areas during nighttime and low visibility conditions. Flashingred lights must be maintained operable at night. 25
    26. 26. Singapore Airlines B-747-400 Construction Related AccidentSingapore Airlines flight SQ006 to Los Angeles, crashed on takeoff from Taipeis ChangKai Shek International Airport at 23:18 local time. The weather in the area was rapidlydeteriorating due to an approaching typhoon. At 140 knots, the 747 impacted concretejersey barricades and several pieces construction equipment, causing the aircraft tobreak into 3 parts and igniting a large post-crash fire. There were 83 fatalities (24Americans) out of 179 passengers and crew. 26
    27. 27. Singapore Airlines B-747-400 Construction Related AccidentThe flight crew mistakenly attempted takeoff on Runway 5R instead of assigned Runway5L. Runway 5R was closed for construction at the time of the accident, however, therunway was not barricaded at the takeoff end because that portion of the runway wasbeing used as a taxi route. 27
    28. 28. Taxiway Safety AreasIn some situations, taxiways may need to be temporarily closed or restricted tosmall aircraft only when adequate wingtip clearance is not available. Barricadesalso do not meet requirements of the AC. 28
